Mark Crandall, Go HighLevel Expert: Featured on HighLevel Spotlight Sessions and Interviewer of Co-Founder Shaun Clark

October 19, 2026•4 min read

HighLevel put me on its own show. Then I sat down with the man who co-founded it.

I built my marketing start to finish on Go HighLevel, and I build every client’s testimonial system inside it. If you are looking for a Go HighLevel expert who uses the platform to turn happy customers into your sales team, this page is the proof.

Featured on HighLevel Spotlight Sessions

HighLevel invited me onto Spotlight Sessions, its own show on the official HighLevel YouTube channel. In “Mark Crandall On Taking Equity In Your Market,” I talk about growing a roofing company to the point of taking ownership in it, and why learning your industry changes the way you market.

My Interview With HighLevel Co-Founder Shaun Clark

After that feature, I interviewed HighLevel co-founder and CEO Shaun Clark on episode 88 of The Purpose Chasers, “Why Go HighLevel Said No to Everyone but Agencies.”

We talked about why HighLevel went agency only, how co-founder Robin Alex earned his equity without asking, a community that polices itself, shipping features every week, and what building a company asks of a marriage.

What I Build Inside Go HighLevel

I do not use HighLevel as a funnel toy. I use it to make sure your best customers never go silent. For my clients that looks like:

  • Testimonial requests that go out the moment a job or program wraps, at the peak of the feeling

  • Review requests and missed call text back so no lead slips through

  • Nurture emails and texts written from your customers’ own words

  • Landing pages, forms and calendars that book calls without the back and forth

  • SEO blogs built around real client stories, like the ones on this site

  • Pipelines that show exactly where every lead stands

All three of my sites, thehappycheck.com, scaletosaleconsulting.com and thepurposechasers.com, run on HighLevel: the blogs, funnels, forms, calendars and automations.


Clients I Have Built on Go HighLevel

Sarah Jones had wanted to get her business online for a long time and did not know how to start a landing page. We built two full landing pages and every automation in Go HighLevel, then recorded a walkthrough so she was comfortable running it herself. In her words:

"He did a great job and I'll definitely be using him again."

Justina Reaves is a public speaker, a coach and a top leader in network marketing. When 2020 hit she had to get her business online, but she did not have time to learn funnels, leads and drip campaigns. Her verdict:

"Mark has transformed my vision into reality."
